I'd definitely recommend Tune Technic, Dave is knowledgeable, a great guy and communication is great. I've had my DSG tuned by them, and what a world of a difference it has made, Dave knows what he's doing. Best of all, he comes to you. It was so easy to deal with him and get things done. 10/10

Rexton 2006 should of done this when I first got it. Where it used to slow down going up a hill it now stays at 100 km/h. Much more torque in the midrange. Also it used to blow out lots of black smoke when passing but the chip increases turbo boost and it has stopped that completely. Have just been from Rangiora to Picton-Nelson 634.6 kms on 55.55 ltrs= 8.75ltr/100k. More than it has ever done before. Make sure you clean the boost sensor in the inlet manifold for accurate readings for the ECU.
